I wasn't at MIR when you were. Silly boy, I don't remember what tires you're running. And if you don't fix the brake issue you really have no need to know!

I am running the original ET Street drag tire and the brake issue I had this past weekend just prevented me from stalling the car much above 2800 rpm. Most of the guys that have posted in here though say they are only stalling to 1200 to 2000 rpm or so and they are still cutting better 60's than me.

 

2,000 rpm with a 3,600 vig and 3.73s gives me consistent 1.60s and good reaction times.

 

The thread below will give you an example of the difference between the tight SS3600 and the SS4000 in the same "DA".

We had an LS1 guy that ran 11.58 a few months back with a 1.58 60 on a SS3600, run 1.65's and 11.8's when the DA returned to normal this time of year. So, you also have to take peoples 60's with a grain of salt, even with very similar combos.

Years back, a friend had full lengths, ORY, pulley, Lid and with a Yank ST3800 (no longer made) and went 12.3-12.5 all day long, on his 98LS1 and 1.65ish 60's. That converter was as loose as a SS4000 (as far a drive ablity is concerned) and flashed almost as high.

I've seen a ton of cars with similar mods to you and tight verter do 1.7 to 1.76 60 foot with 3.23 gear rear. If you want to go faster 60, your going to have to loosen that verter up, add more power or take weight out.

 

I don't think your times are all that bad. It may just take more time out there. I'd try stalling a little lower, like 2500, so that you know it's not going into second when you stage and stall. YOU'LL KNOW WHEN YOU LEAVE IT FIRST

 

1.6's, never gotten any better no matter what rpm i tried launching at so I just go off idle.
